PROTECTIVE ,COV ERIN G OR CASING FOR PIPES.

Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed April 26, 1919. Serial No. 252,780.

To all whom it may concern:

Be it known that I, MAURICE A. NEAMES, a citizen of the United States,and a resident of Gramercy, parish of St. James, State of Louisiana,have inventedcertain new and useful Improvements in Protective Coveringsor Casings for Pipes, of which the following is a specification.

My invention relates to a protective covering or casing for pipes,conduits, mains and for fire-proofing of building columns and the like;and, more particularly, to a covering or casing for pipes, conduits andmains exposed to deteriorating influences, such, for example, as extremeheat, moisture, acids and gases.

The object of my invention is to protect pipes, conduits, mains andother pipe installations from the deteriorating action of high heat,moisture, gases and acids by means of a two section protective coveringor casing with novel clamping and supporting features, the whole beingextremely simple in design and construction, quickly and with thegreatest facility adjustable in place over the piping whereverinstalled, and which may be manufactured with a minimum of operationsand at correspondingly low cost.

The invention itself consists of the novel features of design andconstruction in the various applications of the preferred embodimentthereof illustrated in the accompanying drawings, in which similarcharacters of reference indicate corresponding parts throughout theseveral views, and in which Figure 1 is a side view of the pipeconstruction applied to an elbow connection, taken on a verticalplanepassing through the longitudinal aXis of the case, the incased pipebeing shown in full outline.

Fig. 2 is an end view of the pipe protector construction showing thecasing in full outline and illustrating the end clamping and supportingmeans.

Fig. 3 is a side view in elevation of my protective covering applied toa- T connection, taken on a vertical plane passing through thelongitudinal axis of the casing, the pipe being shown in full outline.

Fig. 4- illustrates in plan View, partly in section, the method ofapplying a plurality of sections of my protective covering end to end ona straight run of pipe.

Fig. 5 is a side view in elevation of the metal clamp and fasteningmeans by which supported on the Referring to the drawings, the inventioncasing 7, molded of refractory tile or other suitable material to meetspecial require ments. The casing 7 is composed of two like halfsections 8 and 9, in Fig. 2 shown joined to ether and may be made fromthe same mold.

The casing 7 is shown in F 1 and 2 shaped to fit an elbow union betweenvertical and horizontal pipes 18 and 1? respectively; in F ig. 3 a stylecasing is illustrated suitable for a T connection between vertical andhorizontal pipes 18 and 17 respectively, and in Fig. 4 the casing 7 isshown applied to a straight run of pipe, a plurality of sections beingpositioned end to end. scription of the casing'l, given in the followingfor the elbow connection shown in Figs. 1 and 2, will also serve todescribe the modified forms thereof illustrated for the T connection andstraight run of pipe, Figs. 3 and 4 respectively, as the details ofconstruction in each are the same.

Each of the longitudinal half sections 8 and 9 of the casing 7 is moldedwith interior and end recesses, which, when the sections are fittedtogether, form interior cavity-lO and end cavities 11 and 12. Cavity 10serves both to reduce the weight of the construction and to furnish adead air space necessary, for example, when the covering is used as aprotection for the blow off pipe of a boiler. End cavities 11 and 12 areformed by the end recesses of the sections 8 and 9 when broughttogether, and these cavities are so shaped, and are of such dimensionslaterally and in depth, that they will each receive themetal clampingand supporting members 13, which, when in position on the pipes and insaid end cavities, serve to lock the sections 8 and 9 together composingthe casing 7, and to secure the casing to the pipes.

The metal clamping and supporting member 13 is made up of two like halfsections 13 and 13 in Fig. 5 shown joined in horizontal axial plane 20,each half section carrying like male and female dovetailing 14 and 15for locking the sections together. Sections 13 and 13 are identical andmay be cast from the same pattern, and are hence in vertical axial plane19,'

its preferred form comprises a sectional The deinterchangeable andeasily matched for assembly. A central opening 16 in the clamp 13, andlengthwise thereof, is provided, the diameter of said opening being suchthat the clamp may be closely fitted over the pipe to be covered.

The ends and the longitudinal seams of the case 7 are covered withcement, clay or other suitable material, thus sealing the casing withthe clamps and supporting mem bers completely covered and embeddedtherein, rendering them free from external deteriorating influences.

It will be noted that the cross section of the casing 7, shown in Fig.2,is made oval in shape, the object of which is to reduce the weight ofthe construction; and, further, when the casing is applied to a boilerblow off pipe, the oval cross section will present as small a surface tothe backward flow of furnace gases as possible, thus affording a freeregress to the gases than where a brick casing 1s employed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent.

1. A protective covering or casing for a pipe of the class described,comprising, in combination, a sectional unit of refractory or protectivematerial, an end cavity in said unit, and means for locking the sectionsof said unit together and for supporting the said unit on the pipecomprising a member fitting into said end cavity, said member beingprovided with a central opening of dimensions to fit the exterior of thepipe.

2. A protective covering or casing for a pipe of the class described,comprising, in combination, a two section unit of refrac tory material,an end cavity in said unit, and means for locking the sections of said.unit together and for supporting said uniton the pipe, said meanscomprising a two section member fitting into said end cavity, saidmember being provided with a central opening of dimensions to fit theexterior of the pipe.

3. A protective covering or casing for a pipe of the class described,comprising, in combination, a two section unit of refractory material,end cavities in said unit, and means for locking the sections of saidunit together and for supporting said sections on the pipe, said meanscomprising a plurality of two section members fitting into said endcavities, said members each being provided with a central opening ofdimensions to fit the exterior of the pipe, and interengaging means forlocking the sections of said members together.
